ART OF MAKING PAPER BOXES.

esa res. 7

To all whom it may concern.

Be it known that I, HARRY W. Jones, a citizen of the United States, residing in San Francisco, in the county of San Francisco and State of California, have invented a new and useful Improvement in the Art of Making Paper Boxes, of which the following is'a specification. V v

This invention relates in general to paper boxes and has more particular reference to boxes of this character made of corrugated board or other stiff material and intended for use as shipping containers. It will, however, be manifest as the invention is better understood that it has a broader and more general application, being capable of efficient use in numerous other connections.

A principal object of the present invention is the provision of a strong and durable box of the character described which may be constructed from blanks cut from a. sheet of material without any waste of said sheet in the production of successive blanks.

A further object of the invention is the provision of a box of this character which will have strong overlapping flaps at its open side or sides, said flaps being particularly formed to resist rough handling in transit.

A further object of this invention is the provision of a box in which the corrugations, if the box be made of corrugated board, will be disposed obliquely in-the side walls or obliquely in the flaps and preferably in both.

A further object of the invention is the provision of a suitable and simple process for constructing a box embodying my invention which may be practised without waste of any of the box-forming material.

Other objects and advantages of the invention will be apparent as it is better understood from the following description when considered in connection with the accompanying drawing illustrating a preferred embodiment thereof.

On the drawing,

cutting and scoring of the blanks shown in Fig. 2;

Fig. 4 is a perspective View of the blanks secured together and ready for formation into the finished box ;-and

Fig. 5 is a perspective phantom view of a finished box embodying my invention.

For the purpose of illustrating my invention I have shown it embodied in a box of the well known elongated rectangular form. This box consists of end walls 6, side walls 7, end wall flaps 8 and side wall flaps 9. The blank is made of two parts, each comprising one side wall 7, one side wall 6, two end flaps 8 and two side flaps 9. Adjacent vertical edges ofthe side and end walls are secured together by adhesive strips 10 at diagonal vertical edges of the box. Each end flap 8 is equal in superficial area and configuration to substantially one-half of the top or bottom of the container and the edges 11 of these flaps abut when closed in a diagonal line as seen in Fig. 5. The same is true of the edge flaps 9 of-the side walls, which also abut in lines obliquely angular with the edges of the box as indicated at 12 in Fig. 5. The corrugations 13 in the flaps and in the side and end walls of the body are preferably obliquely disposed with respect to all the box edges, so that none of these edges can fold in parallelism with the direction of the corrugations. This gives added strength to the box and reduces materially any likelihood of breaking along the bends or score lines.

As has been stated, this box is constructed of two portions, each of which portions is formed from a single blank of trapezoidal form, as shown in Fig. 2. This blank has a central portion extending from one parallel face to the other, of width equal to the height of the box and of length equal to the combined lengths of the horizontal or lateral edges of an end and side. It is scored transversely at a to provide an end 7) and a side a, the end 7) being located adjacent the longer horizontal side. The in clined edges of the blank are determined by passing lines through points located as will now be described, the location of these lines giving the proper edge shapes to the side and cover flaps. The line at each side passes through one point (Z located outwardly of the center of the portion of the said score .cated opposite line defining the lateral or horizontal edge of a side equal to a distance one-half the length of the portion f of this line defining a lateral or horizontal edge of an end I). The line passes through a second point g lothe center of the portion f of the line defining a lateral or horizontal edge of an end I) a distance equal to onehalf the length of a portion 6. The blank thus formed is scored along the lines 0, 7 and a and is cut in from the sides along the line a produced to the central portion as indicated at h. The blanks thus provided are laid reversely upon each other as indicated in Fig. 4 with the central portion of the one blank over the central portion of the other. In this position the adhesive strips 10 are applied to secure to ether the end and side edges thus broug t in adjacent relation. When thus constructed the combined blanks may be readily opened up by bending on the score lines and the flaps folded down into the position shown in Fig. 5.

These blanks may be provided without waste of material from a continuous sheet of corrugated board, cardboard or other box forming material by cutting the strip obliquely as indicated at 13 in Fig. 1, the cuts thus formed being straight and making an angle A with a side edge equal to the angle A between the longer parallel edge of the trapezoidal blank and its adjacent inclined edge. The strips thus cut may be cut in halves, in quarters or in any even fractions along lines of proper inclination to provide a plurality of blanks from each strip. When thus cut the corrugations, lengthwise or across the parent sheet or strip, are disposed in the trapezoidal portions abliquely with respect to their parallel sides, bringing them in the box in the desired relation, 71. e. obliquely with respect to the edges .of the box proper.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing any of its material ad-' vantages, the form hereinbefore described being merely a preferred embodiment thereof.

The described articles are not claimed herein, being the subject of my application, a division'hereof, filed Jan. 2,-191'7. I

I claim:

1. The process of making paper boxes, from a continuous strip of material and without waste, which consists in cutting said strip into a plurality of trapezoidal sections, scoring and cutting said sections into approwithout waste,

which either run passing through points priate blanks from which the box may be constructed and securing said sections together with the shorter parallel side of one section coinciding with the longer parallel side of the other section.

2. The process of making paper boxes from a continuous strip of material and without waste, which consists in cutting said strip along angularly disposed transverse lines, dividing the ortions thus produced into trapezoidal sections, scoring and cutting said sections into appropriate blanks to be used in the finished box.
